HENRY B. KEIPER, OF LANCASTER, PENNSYLVANIA, ASSIGNOR OF ONE- HALF HIS RIGHT TO JOHN M. KEIPER, OF SAME PLACE.

IMPROVEMENT IN COMBINED LEVER ROTARY MOTION BY IMPACT.

, Specification forming part of Letters Patent No. 216,794, dated June 24, 1879; application iiled March 6, 1879.

To all whom it may concern Be it known that I, HENRY B. KEIPER, of the city of Lancaster, Lancaster county, and State of Pennsylvania, have invented certain Improvements in OombinedLever Rotary Motion by Impact,`of which the following is a specieation.

The object of this invention is to connect a vibrating arm or lever with a combined campulley and case or flanged hub of a ily-wheel,

I which severally and jointly revolve loosely upon adead or xed shaft in such a manner ,art to make and use the same, and in which- Figure 1 represents the front or side elevation of thev wheel, Ste.; Fig. 2, an end view, showing the two standards, Src.; Figs. 3 and 4,-detached portions, enlarged, central hub and pulley-cam.

The standards A A', on a base or floor, B, support a fixed shaft, S. On this shaft the wheel C, having a case-like flanged hub, D, sits loosely, so as to revlve freely. A sleeve, R, is shown, to which a fan, strap-pulley, or cogged wheel may be attached to propel other gear.

. Into the open case of the hub D is fitted the raised cam H on the disk E, which latter overlaps and covers the rim of the hub-case -D. This raised cam extends to the bottom of ber within the case of the hub D when in The outer face of the disk E has cast place. with it two ianged pulley-like strap-holders, F Gr, and flanges fg, the whole forming what Iterm a angedpulley 77or doublepulley and cam. This latter combined cam arrangement is disconnected from the case D, and also sits loosely upon the fixed shaft S with the hub of the wheel.

To give motion to the wheel C, or its equivalent, I use two straps, M N, the end of one being attached to the end of a levenarm, L, on one side of the fulcrnnrarm l?, and the other a like distance from the fulcrum on the other side. This fulerum-arm 1 may be above or below the wheel, with its strap-connection simply reversed on the pulleys, and the lever answer for a treadle, one of the straps being coiled around one of the pulleyspaces, say, strap N on space F. The lever being now raised, and the strap M connected with space Gr unwound and drawn tight by a strong downward pull of the lever, the strap M in unwinding necessarily turns the cam-pulley, and the balls I in quick succession impinge against the hub-case orinner periphery, which gives motion to the wheeler case D with great energy and runs it at a high speed. At the same time, at tle end of the stroke or pull, the lever, by the weight w, rises into position for another ilnpulse, uncoiling the one strap and re-coiling the other. hile the cam, balls, and pulleys rest the` impulse given to the wheel continues to revolve it for a length of time corresponding to the resistance.

A spring might be employed to restore the lever ready for a stroke.

I am aware that balls or wedges, in combi` nation with eam-hubs, have been used to pre vent retrograde motion, as also clutches on a curved lever between the rim of thehub or case and spool or pulley, operated by a single cord-an arrangement I disclaim; butlam not aware that a double-cam pulley operated by two straps in this manner were ever before known or used for propelling a fan or wheel, as herein shown and specified. I now drive a fan in a case or blower for a forgeiire, where the ianged hub and pulleys are on one side of the case, and the fly-wheel on the outer end of the sleeve R of the fan, cam, and pulley appliances h'erein set forth, which can be I actuated by the strap and hand-hold direct, and react upon the strap of motion by a spr ngconnection. i
